The thermal break Thermostop shim and fixing head can be used with the LR 80 and
Fixing principle : The vertical aluminium members undergo thermal expansion during
diurnal cycles. Under 3 metres, the linear expansion is within the plasticity of
the system, and does not need special consideration. Once aligned, the vertical
element -T or L extrusion - is riveted to all the brackets using the round holes
provided. All the brackets transfer the self weight of the facade, as well as the
Above 3 metres, rivets are affixed in the same way to the topmost brackets - over
a vertical distance not exeeding 3 metres providing the fixed points transferring
the weight of the rain screen to the primary structure. The brackets below the fixed
points only provide restrain against wind loadings. In this case the rivet is affixed
through the slot holes in the bracket.
At the junction with a lower course, an LR150 bracket is used, with the top course
riveted through an oblong hole, and the lower extrusion riveted through a round hole
in a fixed vertical position. A 6 mm gap is maintained between the two in line extrusions.
Spanning floor to floor lends itself to offsite fabrication of the wall units: The
cladding grid becomes independent from other work packages.
The system consists of a base plate, two friction brackets and a mullion. The system
has the capacity required to fix heavy facade materials such as terra cotta.
The facade material is either face fixed to the vertical element or adjusted in position
using the horizontal railing described below.
Concealed fixing of rain screen cladding
The C rail system allows for fine gap adjustments by means of setting screws situated
on the hooks affixed near the top edge of each panel.

Thermal break : When the insulation is outside of the primary structure, it’s overall
performance is improved by using the nylon base and cap Thermostop as illustrated.
